First BIAB, low OG, Why?

[Bribie G]

Mash temperature shouldn't affect OG, just that the OG will include varying proportions of fermentable / unfermentable sugars.

Thanks so much for all your responses. I've tweaked my BS2 profile to more accurately represent my process from what I learnt on the day and now I'm only a few points off with a 70% efficiency.

Certainly looks like I have a Sh!t tonne to learn and just when I was getting comfortable with extract. I'll take on board all you tips and hopefully have a more accurate brew day next time. Thanks again all.

It is a bit to learn but you'll be amazed how quickly it all comes together. Once you've got 5 or 6 brews under your belt it will be like clockwork!

Not to say there isn't a lifetime of learning that's possible but you can make great beer without understanding all of the technical elements of brewing.
